Obstruction of left anterior descending artery (LAD) due to the thrombosis or atherosclerotic plaques is the leading cause of death worldwide. Targeted delivery of drugs through micro- and nanoparticles is a very promising approach for developing new strategies in clot-busting or treating restenosis. In this work, we modelled the blood flow characteristics in a patient-specific reconstructed LAD artery by the fluid–solid interaction method and based on physiological boundary conditions. Next, we provided a Lagrangian description of micro- and nanoparticles dynamics in the blood flow considering their Brownian motion and the particle–particle interactions. Our results state that the number of...

Atherosclerotic plaques and thrombosis are chronic inflammatory complications and the main manifestations of cardiovascular diseases (CVD), the leading cause of death globally. Achieving non/minimal-invasive therapeutic means for these implications in the coronary network is vital and has become an interdisciplinary concern. Accordingly, smart drug delivery systems, specifically based on micro- and nanoparticles, as a promising method to offer non/minimal-invasive therapeutic mechanisms are under active research. Notably, computational models enable us to study, design, and predict treatment strategies based on smart drug delivery systems with less time and cost compared with conventional...
